The [[Introduction|Introduction to Haskell]] on the Haskell website tells you what Haskell gives you: substantially increased programmer productivity, shorter, clearer, and more maintainable code, fewer errors, higher reliability, a smaller semantic gap between the programmer and the language, shorter lead times.  There is an old but still relevant paper about [http://www.cse.chalmers.se/~rjmh/Papers/whyfp.html Why Functional Programming Matters] (PDF) by John Hughes. More recently, Sebastian Sylvan wrote an article about [[Why Haskell Matters]].

This portal points to places where you can go if you want to learn Haskell.

Join the Haskell subreddit, where we do regular Q&A threads called Hask Anything (that's the archive).

You can ask questions to members of the Haskell community on Matrix, mailing lists, IRC, or StackOverflow.

To get started, set up your Haskell environment. You can also try out Haskell in your browser on the Haskell Playground!
